Abstract
The present invention relates to a kind of synthetic methods of fluorine-containing polyethyleneimine.The fluorine-containing polyethyleneimine is prepared by polyethyleneimine and perfluoroalkyl carboxylic acid halides or the condensation of per-fluoroalkyl sulfonyl halogen.Preparation method are as follows: polyethyleneimine is dissolved in solvent, perfluoroalkyl carboxylic acid halides or per-fluoroalkyl sulfonyl halogen are added dropwise into reaction system in a heated condition, removes solvent after being stirred to react, obtains the fluorine-containing polyethyleneimine cross-linked material.The material can be applied to the fields such as the preparation of seperation film, the preparation of adsorbent and gene transfection Materials, have the performances such as solvent resistant, acid and alkali-resistance, antipollution.
Description
Technical field
The invention belongs to macromolecule modified technical fields, and in particular to one kind can make seperation film, adsorbent, gene transfection material
The synthetic method of the fluorine-containing polyethyleneimine of material.
Background technique
Fluorine material has the characteristics such as excellent thermal stability, chemical stability and low-surface-energy, with polytetrafluoroethylene (PTFE), gathers
Vinylidene is that the fluoropolymer of representative has mature application in terms of separating film preparation.Fluoropolymer is in all multi-solvents
In dissolubility it is poor, traditional phase separation method is unable to satisfy the exploitation demand of a greater variety of fluoropolymer seperation films.Closely
Nian Lai has the document and patent report that functional fluoropolymer film is prepared using water-soluble preferable fluorine-containing cross-linked material successively.Middle promulgated by the State Council
Bright patent ZL CN 2 201010589192.6 " film function monomer and its nanofiltration membrane preparation method containing hexafluoroisopropanol group "
A kind of cross-linked material of function monomer containing hexafluoroisopropanol of middle invention with acyl chloride material by interface-cross-linked, it is anti-by controlling
Condition optimizing is answered to go out fluorine-containing nanofiltration membrane, prepared fluorine-containing nanofiltration membrane is preferable to bivalent cation and anion rejection effect, and
And there is very strong resistance to free chlorine oxidation susceptibility.Li Yafei, Jiang Zhongyi et al. pass through the condensation of triethylene tetramine and perfluoro caprylic acid
Reaction prepares the fluorine-containing polyamine in water-soluble, passes through the amido and polyamide film surface carboxylic acid in fluorine-containing polynary amine structure
Condensation in nanofiltration membrane surface modification full-fluorine group, the fluorine-containing nanofiltration membrane show fabulous antifouling property (Y. Li et al,
J. Membr. Sci, 2014,455,15-23.).The fluoropolymer used in foregoing invention suffers from preferable water-soluble
Property, it is suitable for more film-forming methods.
Polyethyleneimine is a kind of Polycationic water soluble polymer, has linear and two kinds of branched knots
Structure, there are a large amount of amidos in skeleton, and wherein primary amine, secondary amine, tertiary amine ratio 1:2:1 in branched polyethylene imine structure, have
Fabulous reactivity.Polyethyleneimine can prepare microballoon such as Chinese patent by being crosslinked other small molecules
ZL201110140086.4, United States Patent (USP) US2010/0267108A1 etc. or thin-film material, in gene transfection Materials, adsorption material
There is more application in material, separation membrane material, active amine can carry out a variety of chemical modifications in structure.Chinese invention patent
One has been invented in ZL CN 201610584829.X " a kind of the PEI compounds of modification and its preparation method and application "
The primary amine hydrogen in polyethyleneimine that the PEI compounds of kind modification are 1.8k to molecular weight by heptafluorobutyric anhydride replaces
It obtains, can be used as excellent genes delivery system.However heptafluorobutyric anhydride higher cost, how by fluorine-containing reagent and reaction
The screening of condition, preparing, there is water-soluble, low cost fluorine-containing polyethyleneimine turn it in seperation film, adsorbent even gene
Contaminating the fields such as material, specifically better application prospect is problem to be solved of the present invention.
Summary of the invention
It is an object of the invention to solve the scarcity of the fluorine-containing cross-linked material of water-soluble low cost, providing one kind can be used for point
The preparation method of novel low-cost functional fluoropolymer material from film preparation, gene transfection Materials and adsorbent material.
The present invention is achieved through the following technical solutions:
A kind of structure fragment general formula of fluorine-containing polyethyleneimine functional material is as follows:
Wherein dotted line represents N atom connection branch or hydrogen, Z be sulfonyl () or acyl group ();R is perfluoroalkyl,
General formula CnF2n+1, n 1-18.
A kind of preparation method of fluorine-containing polyethyleneimine functional material, includes the following steps, polyethyleneimine is dissolved in
In solvent, perfluoroalkyl carboxylic acid halides or per-fluoroalkyl sulfonyl halogen are added dropwise into the solution, in a heated condition, after being stirred to react
Solvent is removed, the fluorine-containing polyethyleneimine material is obtained.
The preparation method of fluorine-containing polyethyleneimine material according to the present invention, polyethyleneimine are substrate, molecule
Amount is 600 Da, 1800 Da, the one or more of 10000 Da and 70000 Da;
The preparation method of fluorine-containing polyethyleneimine material according to the present invention, related fluorination reagent perfluoroalkyl acyl
Halogen general structure is, per-fluoroalkyl sulfonyl halogen general structure is, wherein R is perfluoroalkyl, general formula
